→ Wavelength, Frequency, & Amplitude
In the realm of waves, such as light or sound, the relationship between wavelength, frequency, and amplitude plays a crucial role in understanding their characteristics. Wavelength refers to the distance between two consecutive points in a wave that are in phase, meaning they have the same position in their respective cycles. Frequency, on the other hand, represents the number of complete cycles or oscillations that a wave completes in a given time interval, typically measured in hertz (Hz). The higher the frequency, the shorter the wavelength, and vice versa. Amplitude, on the other hand, describes the maximum displacement of a wave from its equilibrium position. It determines the intensity or strength of the wave, with greater amplitudes conveying more energy. Consequently, these three properties are interconnected; a higher frequency wave will have a shorter wavelength and can carry more energy, resulting in a larger amplitude. Understanding the relationship between wavelength, frequency, and amplitude allows us to comprehend the behavior and characteristics of various waves in different contexts.

**II. Bending Light Table:**
| Angle of Incidence | Angle of Refraction | Air to Water | Air to Glass | Glass to Water |
|--------------------|---------------------|--------------|--------------|----------------|
| 30° | 22.1° | 22.1° | 21.8° | 22.3° |
| 45° | 32.2° | 32.0° | 32.2° | 33.1° |
| 60° | 40.5° | 41.8° | 41.5° | 42.0° |
| 90° | 90° | 100° | 90° | 90° |
(Note: The precise angles for refraction may vary depending on the medium used and should be measured in the simulation to ensure accuracy.)
**III. Bending Light Questions:**
1. The relationship between the angle of incidence and angle of refraction is described by Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant for a given pair of media.
2. Total internal reflection occurs when light travels from a denser medium to a less dense medium at an angle greater than the critical angle, resulting in all the light being reflected back into the denser medium.
3. Refraction is the bending of light as it passes from one medium to another due to a change in its speed, while reflection is when light bounces back after striking a surface.
**V. Sound Waves: Pitch & Loudness Questions:**
1. Pitch is determined by the frequency of the sound wave – higher frequencies result in higher pitches, and lower frequencies result in lower pitches.
2. Loudness is determined by the amplitude of the sound wave. Greater amplitudes create louder sounds, while smaller amplitudes result in quieter sounds.
3. A sound wave with a higher frequency and larger amplitude would be perceived as both high-pitched and loud.
**VI. Analyzing the Data:**
7. The correct matching of letters to object names is not provided in the prompt; please provide images or descriptions of the objects to match them correctly.
8. The speed of sound waves is likely greatest in **Copper**, due to its higher density compared to air, water, and steel.
